7-73 Muhammad ibn al-Hassan - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted Muhammad ibn Ahmad ibn Yahya ibn Imran al-Ash’ari, on the authority of Al-Sayyari, on the authority of Muhammad ibn Ahmad al-Daq’qaq al-Baghdady,

“I wrote a letter to Abal-Hassan - the second - that is Al-Ridha (MGB) and asked him about traveling on the last Wednesday of the month. He (MGB) replied, ‘Whoever travels on the last Wednesday of the month in order to invalidate the claim of those that this act has bad omen will be safe from all calamities.God shall fulfill his needs.’ I wrote another letter to him (MGB) and asked him about blood-letting on the last Wednesday of the month. He (MGB) replied, ‘Whoever has phlebotomy done for him on the last Wednesday of the month in order to invalidate the claim of those that this act has bad omen will be safe from any calamities or ailments. The place of blood-letting shall not turn green.’”
